The results of uncertainty regarding the estimate of mean survival time.
The uncertainty was captured in the following situations: Weibull distribution: A. γ = 0.6, censoring rate = 0.76; B. γ = 1, censoring rate = 0.76; C. γ = 1, censoring rate = 0.26, and lognormal distribution: D. σ = 2, censoring rate = 0.26.
